First jutsu:(Senpo Katon: Dai Endan) – Sage Art Fire Release: Big Flame Bullet
A sage powered fire ball. It's good because it is oil based, so that means it will naturally be hotter than a normal fire ball plus the sage chakra in it. Like most fire projectiles, you want to use them in conjunction with another jutsu so they can empower each other. Needing to be in SM to use it is a bit of a disadvantage, though there are some non-sm jutsu that are similar. I'd probably just use this technique for RP purposes or to simply overpower something. The simpler techniques like this are a bit tougher for me to think of creative ways to use them, since i'd usually use techniques that are a bit more versatile to make combinations with.
(Senpo: Futon Sunabokori) – Sage Art: Wind Release Dust Cloud
Usable bt Shima. I'd use this jutsu when i'm in close to a target. With Shima kicking up the dust and blocking all vision I would rely on my senseing while in SM and speed to blitz the target, coming in and out of the smoke too fast for them to see and react. Is also good for setting up a plan - such as hiding a clone to gather energy if you summon just Ma on her own. Since it is big enough to cover a summoning you could use it to hide large scale jutsu too.
It's oil fire, what happens when people add water to burning oil? That's the best part of this jutsu to me. Also it can cover the field in burning hot oil to slow people down
Second:
Also, it can counter sharingan in close combat, get ma to use this dust in their eyes, they wont be able to open them. And so you take out doujutsu power. Not only this but you can combine it with clones, use dust, use clone to go out and distract. Or like use dust and then follow up with pa's tongue jutsu while they can't see it (you will learn this next i think)
